Designing the User Interface.: Strategies for Effective Human-Computer Interaction (Taschenbuch)

This book is presented as a textbook and some people may have a problem with this approach. The fact is most of the people studying User Interface are PhDs and they need to sell these things to their students so they can continue making their bar tab in the faculty lounge.

'Designing the User Interface' covers as much human-computer interaction as you could hope to fit in a textbook. You may be left wondering why anyone would bother writing a book about the same subject again. It's already covered. Unfortunately, most of the textbook will be too 'academic' for our purposes. If you want to know about computer science, psychology, information science, business systems, education technology, communications arts, media studies, technical writing, research agendas, you'll find it. But just flip to the obvious throw-in Chapter 16, titled: hypermedia and the worldwide web on page 551. That's what I did. In fact, the other obvious throw-in titled 'Afterward' has some great sections such as 'Ten Plagues of the Information Age' and 'Between Hope and Fear.' Shneiderman waxes philosophical here on the big picture of human-computer interaction. He covers subjects such as universal access, fear of technology, professional responsibilities, alienation, unemployment and displacement.

My personal viewpoint is that text is much a part of user interface as graphics and navigation. Unclear text makes it just as hard for a user to interpret a site as mauve navigation buttons on a brown background. So why do User Interface experts present sentences such as:

"In the last 40 years, the cathode ray tube (CRT), often called the visual display unit (VDU) or tube (VDT), has emerged as an alternate medium for presenting text, but researchers have only begun the long process of optimization (Cakir et al., 1980; Grandjean and Vigliani, 1982; Heines, 1984; Helander, 1987; Hansen and Haas, 1988; Oborne and Holton, 1988, Creed and Newstead, 1988, Horton, 1990) to meet user needs." (Page 412)?

Yikers! That's hard to read. Where's the usability in that sentence?

Schneiderman takes an obvious academic approach to Chapter 16. He starts off with the history of the web going back to the 1940s. Don't ask. Then we learn what hypertext is. I think we know where this is going. There is, however, a great photo of Sophia Loren wearing a bathing suit circa. 1955.

He analyzes task-oriented and metaphor-oriented design. This is a good thing because we seem hooked on metaphors without looking at tasks. Perhaps tasks are obvious to us. Maybe task-oriented design means usability But then you have to bring in intuitive response and that opens a whole can of worms.

The pages between 575 and 579 cover general design themes such as clustering, sequencing, navigation and usability testing. They're probably the five most important pages in the book.

Another good section of the book is chapter four. It covers user acceptance testing and offers a great sample assessment survey on page 136. I'd be very interested in running this survey on some of our sites as a test.

I don't want to say the rest of the book isn't valuable to us - it is. It just isn't necessary. Most of it deals in theories predating the web -- possibly predating the mouse.

Shneiderman offers a website companion to the book . It's jam packed with updates, study guides and errata such as: "Page 486, first line Gertude should be Gertrude." At least he's trying to practice what he preaches. But how can I fault a man who's Honorary Doctorate of Science comes from my alma Mata?
